Cannot switch imdb.com website to light mode...

Hi, I use the Safari browser (version 18.1) on a MacBook Pro (November 2023-macOS Sonoma 14.6.1) and there is no obvious mechanism for switching IMDb.com web version from dark mode to light mode. I have eye issues and have trouble using dark mode feature. How can I switch the website version from dark to light using my specific computer/browser?
